%X In this paper, switching behaviors of MQCA inverter and majority logic gate with various nanomagnet thicknesses and spacings are studied. Single domain approximation Landau-Lifshitz-Gilbert equation is employed to model and simulate the circuits. It is shown that thicker nanomagnet needs larger switching magnetic pulse and logic circuits comprised of thicker nanomagnet demonstrate slower switching; majority logic gate needs more time to switch than inverter when they have the same nanomagnet thicknesses and spacings. Moreover, it is also shown that nanomagnet spacing has a larger effect on switching behavior of inverter than on majority logic gate.
